They haven’t appeared in newer titles (thank god) but they have been around.

These roam Pokémon act differently to in PBB. These roam Pokémon appear at a random location on the map and you have to travel to that random location. You can’t fly to the location because that resets the location. Repel trick does work and you trigger a battle. So normally they run away after one turn. Then you have to chase it down again. Very tedious but mean look can prevent this. From there catch like a regular set encounter legendary.
